Application July 1, 1930,.SerialNo. 465,148 Renewed July. 30, 1935 15 Claims;

This invention relates to looks of the typev adapted for use in oflice buildings, hotels or homes where certain definite operations arerequired.

It' is the object of this invention to' devise a single lock which by simple changes in the type of operating mechanism, may be adapted to one of a plurality of uses which may at the moment be desired.

The fundamental principle of my invention resides in the feature wherein a single lock isequipped with the usual types of locking-mechanisms and has its lock operating mechanismso positioned relatively to a pair of cylinder openings on the outside and the inside plates of the lock, that different cylinders, thumb turns, or other operating devices, fitted to the inside or outside plates of the lock will be capable of operating the mechanism in a predetermined manner. Thus, I simply change the type of operating cylinder or thumb turn, selecting one whose movement is limited in extent and in the direction of its turning, or unlimited in either, or any other well known type of operating mecha nism, and thus'obtain any one of a plurality" of operations for which the lock is constructed.

For a further description of my invention, I refer to the drawings wherein Fig. 1 is a plan View of my lock with the cover plate removed. Fig. 2 is a side elevation of the front plate of the lock. Fig. 3 is a section along thelines of 3--3 of Fig. 1. Figs. 4 and 5 are views similar to Fig. 1:, showing some of the parts in various operating positions, and some of the parts omitted. Fig. 4A illustrates the relation of several of the parts. Figs. 6 and 7 are front and side Views of a cylin- "der which may be used in the lock. Figs. 8' and-9 are end views of the cylinder and a modification. Figs. 10, 11 and 12 are front, side and end views. of a thumb turn adapted for the particular lock. Fig. 13 is a section of the thumb turn of Fig. 11. Fig. 14 is a section along the line l4|4 of Fig. 13. Fig. 15 is a section along the line l5l5- of Fig. 13. Fig. 16 is a section along the line I6'-|6- of Fig. 15. Figs. 1'7, 18 and 19 are front, side and end views of the plug device usable with the lock of the present construction. Fig. 20 is a side View of a two cam cylinder which may be used with this invention.

Referring now more particularly to the drawings, and especially to Figs. 1 and 2, I show a usual type of lock casing, designated by the reference numeral l0, having the usual type of front plate II, the usual type of latchbolt l2 and a regulation type of latchbolt deadlocking mechanism' l-3;,all ofiwhich are of the type well known in theart. Forretracting the latchbolt I2, I use a pair ofroll-backs l4 and 15, shown more particularlydnrFig; 3; These roll-backs operate on a lever-device 16: which in turn operates on a lever ll which'operates-on the rear extension plate I8 of v the latchbolt l2 to' retract the same, when either ofthese roll-backs ['4 and I5 is rotated by aknob or other device. This'mechanism is also of. the: usual type, quite well-known in the art.

Cooperating with these roll-backs l4 and I5, are' a: pair of stopwork slides l9 and 20. The inside knob roll-back I4 is controlled-by the slide l9-,-,whereas;-the outside roll-back l5is controlled bytheslide 26; Mounted. on a pin 2| carried by the; lock-,aret a pair. of levers 22 and 23. The lever-22* fits in a. notch 24' in. the outside stopwonk slide? 20 for. controlling the same as is readilyseen inthedrawings. The. lever 23 fits in a notch 215'in1the: inside stop-work slide l9 and operatesthersame in a similar manner. Each of these levers. Hand 23 is equipped with. a cut-out portion 25'foroperation by a pair of levers 26 and 21; Each of these levers 26 and 21 is equipped with: a ledge. 28" and a; spring-pressed tumbler 29, pivoted. thereto at the point 30. Each of these levers 26 and 21 is mounted on a pin 32 against which. the spring 3 I' of the tumbler 29 is adapted to press torurgez the tumbler into an upward position against the lug 36 as is shown clearly in Figs. 1,1? and 5.

From the. relationship of the parts so far deseribed,.it;will.be quiterapparent that the stopworkfor the inside operated roll-back I4 is operated'by the slide I9, and the lever 23, and the upper lever 26, this upper lever 26 being situated on. the side opposite the inside roll-back M; in otherwords on the outside plate of the lock. 0n the other hand, the outside operated roll-back I5: is operated by the slide 20, the lever 22, and the upper lever 21, this upper lever being situated for operation by a cylinder on the inside plate of the look.

For operatingithe stop-work for the outer rollback, I useaa. thumb turn cam 33, the action of which is illustrated in Fig. 1. On the downward swing of this cam 33, from the dotted line positionin. the direction of the arrow 34, it will bypass the spring pressed tumbler 29 and will act on the ledge 28 to depress the same, thereby rotating the lever 22 about its pivot 2| in a clockwise. direction and moving the slide 20 out of roll-back stopping position. When this thumb turn cam 3.3ismovod in a direction reverse to the arrow 34;. it-wi'll impinge upon the tumbler 29,

and since that tumbler cannot move freely relatively to lever 21 in a reverse direction, due to the lug 35, it will act to move the lever 21 back to its position of Fig. 1 and lock the roll-back I5.

Fig. 4 shows the action of a special outside cylinder roll-back cam 36 relatively to the slide l9, and inside roll-back I4, the action being exactly the same as in regard to the thumb turn cam 33, except that the inner stop-work is actuated from the outside, instead of the outer stopwork being actuated from the inside.

In addition to the latchbolt retracting rollbacks l4 and I5, I utilize a second latch-retracting mechanism which may be mounted independently relatively to the roll-backs l4 and I5. This retracting mechanism consists of the lever I! which is utilized in the retraction of the latchbolt by the roll-backs l4 and as has been previously described. This lever I1 is equipped with a portion 31 which is acted upon by a lever 38, pivoted to the case at the point 39, and spring pressed by a spring 40 in a downward direction against the portion 31 (Figs. 4 and 5) The lever 38 is equipped with a cam actuated portion 4|, which extends the entire breadth of the lock and is operable by either the outside cylinder cam 36 shown in Fig. 4 or the inside thumb turn cam 33, shown in Fig. 1. Rotation of either one of these cams in a counter-clock-wise direction will cause the same to strike the head 4| of the lever 38 as is seen in Fig. 5, which will in turn act upon the portion 31 of lever I! to retract the latch-bolt l8 as is clearly seen.

From the above description, it has been shown that my lock consists essentially of a lock having a latch-bolt, inside and outside roll-backs for retracting said latch-bolt, stop-work mechanism for each of these roll-backs, the stop-work for the inside roll-back being operablefrom the outside and the stop-Work for the outside roll-back being operable from the inside. It has also been apparent that the mechanisms for operating this stop-work are so positioned relatively to the cylinder lock mountings of the lock, that they are available for operation by axially aligned cams carried by any type of cylinder which may be put into these mountings. It has been further apparent that my lock is equipped with a latchbolt; the operating mechanism for which may be quite independent of the latch-bolt retracting mechanism, aforementioned, this latch operating mechanism being also positioned nearthe cylinder mountings of the lock so that the cams of any cylinders mounted in the lock may operate the same, provided those camsare capable of the proper amount and direction of rotation.

As willbe readily understood by one skilled in the art, and as is further apparent from the drawings, the inside and outside plates of the lock; in other words, the casing and the cover, are each equipped with cylinder mounting means of the usual type. 'In Figs. 6 to'20 inclusive, I illustrate various cylinders which may be mounted in these cylinder mounting means for securing various operations and for variously controlling my universal lock.

In Figs. 6 to 9 inclusive, I illustrate a cylinder lock 36 of the usual type, having a regular cam 36 such as is shown in the previously described figures. This cam may either have unlimited movement in any direction as in Fig. 9 or may cooperate with a stop pin 42 located for limiting the direction of rotation in a clock-wise direction only. It will be quite apparent from Figs. 1 and 4 that a cam having the limited 'movement'of the cam of Fig. 8 will be capable of operating the stop-work mechanism, but will be incapable of operating the latch operating lever 38, as illustrated in Fig. 5. The pin 42 may be shifted to the right of the cam 36 as shown in dotted lines in Fig. 8 and will then permit operation of the lever 38 but will prevent operation of the stopwork mechanism.

Figs. to 16 illustrate a thumb turn usable with this invention. As may be seen from these figures, the thumb turn is equipped with a handle 43 secured to a body member 44, upon which is secured the cam 45 and the cam body 46. A spring 41 is adapted to cooperate with the body 44 for urging the same into a vertical position, with the cam 45 in either a downward position or in an upward position.

Cooperating with the cam body 46 are a pair of spring pressed pawls 41 which operate in the slot 48 of the cam body 46. There may be only one of these pawls, if certain other action is desired, as will be readily understood. As will be readily understood from Fig. 15, the left member 41 will prevent rotation of the cam in a clock-wise direction, due to its sharp point and will be'operable only to control the stop-' work mechanism should the slot 49 be placed on the right hand side of the member 46 in Fig. 15, it would naturally be possible to control the stop work only.

If desired, the inside or outside cylinder may be replaced by merely a plug 50 as indicated in Figs. 17, 18 and 19 which will simply plug up the cylinder mounting holes in the lock casing, and so prevent operation from the particular side in which it is inserted. Also a master-key cylinder 5| having a pair of cams 53 and 52 as shown in Fig. 20 may be used to obtain still other operations, depending upon the control of the cylinder cams which is determined. Those skilled in the art will readily appreciate the number of operating conditions which may be obtained in this way.

With the arrangement I have shown, it is possible to have any one of a plurality of actions by simply inserting predetermined cylinders in the cylinder mounting means. That is why I call my new look, a universal look. It can be adapted for an ofiice door, a school-house door, a communicating door, a hotel door, or other type of door by simply using the proper cylinders, etc.

Essentially, my invention, therefore, consists in having a latch bolt, latch operating means operable by roll-backs controlled by stop-work, and

an additional latch operating means, the stopwork mechanism and the additional latch operating means all being arranged for operation by a plurality of predetermined arranged cylinder cams, capable of predetermined operations.
